The LHC is back - and it's stronger than ever

After the Large Hadron Collider (LHC) took a 2 year hiatus to up its power, it's finally back, and it's stronger than ever - strong enough to uncover some of physics best kept secrets. Today, June 3, the LhC started delivering physics data for the first time in 27 months.

LHC back in business after two year hiatus: already breaks record

Two years ago, following the discovery of the Higgs boson - heralded as one of the greatest scientific achievements of this century - the Large Hadron Collider at CERN was shut down for much needed maintenance and upgrades. A few days ago, the massive particle accelerator was shifted into gear and powered up. The first test run wasn't only successful, it set a new record by producing collision energies of around 13 trillion electron-volts. The highest speed that was previously achieved was of only 6.5 TeV. More tests will be made throughout the remainder of this month and June.

Stephen Hawking: 'God particle' might destroy the Universe. But wait...

I’m not sure what’s on with Stephen Hawking and his pessimistic view of the world. He’s been known for audacious, panic-inflicting claims like the world is going to be destroyed either by aliens or artificial intelligence, all if we don’t destroy ourselves in the meantime since humans only have 1,000 years left on this planet […]

China plans to build world's first super collider

A group of Chinese physicists, working with international collaborators, have announced their plans of building a  52-kilometre underground particle accelerator that would smash together electrons and positrons to unravel the fundamental building blocks of life. The project would offer means of probing these sort of fundamental questions that are unavailable to the Large Hadron Collider at CERN, an oval-shaped […]

The LHC is gearing up for long-awaited restart

The Large Hadron Collider at the European Organization for Nuclear Research (CERN) is the most complex machinery devised by mankind. Here, scientists all over the world joined forces to recreate conditions similar those in the very first moments of the Universe, following the Big Bang. There’s a lot at stake here, and so far the LHC has […]

Scientists closely working with the  Large Hadron Collider, the largest and most powerful particle accelerator in the world, have identified evidence of the minuscule droplets produced in the aftermath of high energy proton and lead ions collisions. If their calculations are right, then these are the smallest droplets of liquid ever encountered thus far, just three to […]

LHC passes 'hardest' test yet: ping-pong ball blazes through particle accelerator

How do you check a multi-billion dollar particle accelerator for defects or malfunctions? Sure, you could use various, equally expensive and sophisticated tools, but in some instances low tech comes in the aid of high tech, say a ping-pong ball. Wait, what ?! Yup, today researchers  sent a carefully sterilized, slightly-smaller-than-regulation ping-pong ball through a 2-mile […]

Higgs boson discovery confirmed after CERN scientists reviewed massive LHC data

The science of physics has entered a new era once with the discovery of the much sought-after Higgs boson in July 2012.

The Large […]

Hottest temperature on Earth reached after scientists create quark-gluon particle soup

Not one, but two independent high-energy particle physics laboratories in New York (Relativistic Heavy Ion Collider – RHIC) and Geneva ( Large Hadron Collider – LHC) have managed to create quark-gluon plasma after smashing particles into another at very high speeds. The resulting plasma, which only lasted for a fraction of a moment,  is the hottest […]

ISS's Alpha Magnetic Spectrometer is like an LHC in space - already boasting fantastic results

Alright, the analogy might not be the best. The Large Hadron Collider is a high energy particle accelerator, while the Alpha Magnetic Spectrometer is a state of the art particle detector, which traps high-energy charged particles called cosmic rays and analyzes them. You see, the AMS can practically perform the same functions as the LHC, only the high […]

Rumors of imminent Higgs boson announcement run amok on science blogs. Discovery might be announced next week

The Higgs boson or the God particle, as it’s also been commonly referred to, is a hypothetical particle that endows other elementary particles with mass. Confirming its existence is of crucial importance to physicists at the moment, otherwise scientists would be forced to rethink another method of imputing mass to particles.  Last year, scientists at CERN registered a hint; […]

LHC reaches highest energy yet

It’s been pretty quiet lately at the LHC, despite the fact that things seemed to be getting pretty hot, as the elusive Higgs boson appeared to be cornered. However, CERN cracked up the volume, announcing they achieved a record collision energy of 8 TeV. LHC recap The Large Hadron Collider is the world’s largest and […]

Fermilab's Tevatron accelerator hints Higgs boson existance, confirms LHC data

The biggest manhunt in physics history is steadily closing in on its target. Wanted – Higgs boson, also known as the God Particle. Reason – explain why objects have mass and provide “missing link” for standard model of physics. Sketch portrait – mass around 125 GeV. Last seen – Fermilab Tevatron particle accelerator. If you […]

New CERN experiment finds neutrinos still faster than light

The idea which states that nothing can travel faster than light is a corner stone of modern day physics, upon which scientists have built up models and theories of how the world, the Universe, works. If the statement is proven to be false, than our understanding of physics becomes undermined, and as such needs to […]

Particles faster than speed of light put to the test by Fermilab, US

Last week, ground shattering news hit the scientific community worldwide when CERN announced that their experiments showed that neutrinos fired from the CERN laboratory in Geneva, reached their destination of Gran Sasso, Italy, 60 billionths of a second faster than they would have if they had been traveling exactly at the speed of light. CERN […]

People find out that CERN trapped antimatter for over 15 minutes

It always baffles me to see how science news propagate; it seems whenever a study or a report is published, there are two waves of acknowledgement: the first one, science sites and magazines write about it, and the second one, the supermassive one, where the media picks it up. This is exactly the case here. […]

Densest material ever created announced at LHC

The Large Hadron Collider (LHC) continues on its quest to find out exactly what happened in the first seconds after the Big Bang, unveiling what is the densest material known so far to man.

Large Hadron Collider can be the world's first time machine

It’s been a while since we wrote something about the Large Hadron Collider, but this time, some researchers from the LHC come back with a jaw dropping theory – time travel. If this latest theory of Tom Weiler and Chui Man Ho is correct, than the LHC would be the world’s first machine able to […]

Antimatter captured at CERN

For physicists, antimatter is probably the most valuable substance ever; the slightest bit of it could provide extremely valuable information that can help clear out some of the most stressing issues in modern physics. However, the thing is these little gifts are pretty hard to wrap. However, the ALPHA project at CERN achieved this remarkable […]

Large Hadron Collider creates mini big bangs and incredible heat

The Large Hadron Collider at CERN has taken another step towards its goal of finding the so called ‘god particle‘: it recently produced the highest temperatures ever obtained through a science experiment. The day before yesterday, 7 November was a big one at the LHC, as the particle collider started smashing lead ions head-on instead […]

The Higgs boson was initially called the 'goddamn particle'

Peter Higgs is not the rockstar type of scientist; the particle physicist rarely gives interviews, despite the fact that he is the one who proposed the existence of a fundamental particle that gives all matter its mass. Almost as mysterious as the particle itself, he simply calls it the “boson named after me”. Higgs visited […]

LHC - we have a collision !

“It’s a great day to be a particle physicist,” said CERN director general Rolf Heuer. “A lot of people have waited a long time for this moment.” The LHC had been going on a promising streak for quite a while now; however, the encountered problems (mostly engineering, but also physics) were huge. Imagine firing arrows […]
